Abstract

The invention relates to a temperature difference generator utilizing the residual heat of the tail gas of an automobile, belonging to the technical field of regenerative energy. The device comprises a heat collection device, temperature difference power generation pieces and a cooling water tank. The connection of the device is in such a way that the surface of the heat collection device is provided with at least one temperature difference power generation piece, the hot end of each temperature difference power generation piece is connected with the side face of the heat collection device, and the cold end of each temperature difference power generation piece is connected with the cooling water tank. The temperature difference generator has the advantages that the heat collection device is adopted to carry out the heat collection of the residual heat of the tail gas and provide high temperature for the temperature difference power generation pieces, the cooling water tank is used for carrying out heat radiation on the cold ends of the temperature difference power generation pieces, the effect of heat radiation is good, the heat radiation is free from the influence of the outside temperature and seasonal variations, the temperature of the cold ends of the temperature difference power generation pieces keeps constant, and the temperature difference power generation pieces have stable work, simple structure, low cost, convenient use, stable performance and high energy production efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of renewable energy, in particular to a thermoelectric generator utilizing waste heat from automobile exhaust. Background technique: [0002] At present, the number of motor vehicles in my country has reached 166 million, and the amount of fuel is huge every year. However, about 60% of the energy in fuel has not been effectively utilized, and most of it is discharged into the atmosphere in the form of waste heat, causing huge economic losses. and serious environmental pollution. Chinese invention patent CN101436838 discloses a device for generating electricity by temperature difference using a vehicle exhaust pipe. The heat dissipation efficiency of forced convection heat transfer is low, and it is difficult to achieve stable operation in actual application due to the influence of seasonal temperature changes, resulting in low production efficiency of the device. Invention content: [0003] In view of th...
